The G2 or version II was introduced in 2013 as a updated replacement for the very successful (nearly identical other than color) original Sony 70-400mm F/4-5.6 G SSM. The version II has everything people love about the first version but also notable upgrades: a faster more responsive AF system (thanks to a new LSI processor) and Sony's state of the art Nano AR Coating (nano structure anti-reflective coating) which is able to dramatically reduce flare and ghosting (by more evenly transmitting light at wider incident angles to the optical surface). The version II is white and the version I is silver.

The 70?400 mm F4?5.6 G SSM II is an ideal lens for outdoor sports action, wildlife, portraiture, compressed landscapes, and more. Covering an extremely broad telephoto range, this award-winning lens can, take you from an close 70mm portrait to a stunning 400mm action shot in an instant without having to change lenses and potentially miss the moment for a great shot. If you're looking for big lens performance plus extra framing versatility in a reasonably portable package the SAL70400G2 is a great choice.
